The official Game of Thrones Tumblr has just announced a contest for art-inclined fans of the television series. The challenge? Create your own fan poster for Season 3. The rules explain all you need to know about the requirements to participate, as well as the rather substantial prize package with an estimated retail value just south of $5,000 (including the limited edition Iron Throne and the awesome direwolf bookends from Dark Horse.)

The contest runs from now to 12 PM Eastern time on to June 14th, so plenty of time to get to work!
